11 position, the bloc-ring; slide is auto irati cally shifted from its operative position, shown in to its iuopemtive posi in, shown in 2! This slow W takes place prior to the conclusion of the more ent oi the'main opera by; hohdle w actucuig e shaft f on which the di, is with handles Z) are mounted.

' Through my present iiive matic shifting of the blocking; Do ried out in the iollouhw' marin ting shattj' carries i 2, 5, '4', 8) Wh' h I y a lever h '7) which is provided with beveled side 1 adapted. to a correspondingly beveled depending; head i '01:? the blocking slide 0. l /he i the lever is being raised by the cam. g, he blocking slide 0 will be pushed back; length rise into the osition, shown in Fi 5, agais t e resistance of the spri 1 1'; connected Willi the slide 0 to retain thesame in its inoperative position, The cam g is timed so to permit the lever 72; to swing downward sc as all of the settiug up handles I are stored to zero. 'l. he spring; is, them acts '1" press the blocking; slide 0 again into operative phsitiou shown in. Fig. 2.

A stop Z is provided to limit t 1e movement caused under the action of the spr' Ir. However, c stop I is not stationary, but can be caused to swing out of touch with the blocking slide a, through the eucy of:

the handle m provided with out the machine casing. The bloclring slide 0 is, then, able to travel, farther to the leiitto the position shown in 8. ll ith the shaft of the handle m, is positively connected a pin a which engages the lever 7L when the handle an is being; actuated and lifts the same out ofthe control of the cam 9, Thus raised the lever 1 comes into position to the right of the head i and thereby locks the latter against accide" tal displacement, Tie Z is furnished with a beveled side which engages the head i and pushes the some back into the inoperative position shown in 2 when the handle in is returned. Previously to the shift of the blocking slide c the pin permits the lever h. to drop 2 Hence, through manipulation of the haridle m the automatically acting mocha oism for restoring the setting handles Z) to zero position, can be rendered operative and inoperative at will.

Instead of performing a lengthwise shifting: im'nemeht the blocking slide can just as well be adapted to perform a crosswise directed swinging; movement. The alterations; required for such a n'iodified construction are simple in nature and cad he read'l inferred from the \lLEW rcprmluccd in i 12. For this purpose, the blocking slide 11 teerh a? but may tingaip handles do not participate u. the revolvim :ioveuaent of the actuating member but are 'ai'iously {Associated from He opera'iti e tingaip mechanism (complied for restoring the scttiilgaip members to zero position; it is only required to provide projections on the revolving setting-up members so as to coact with the blocking slide in the same manic r as the revolving SGill-ll'lgjfllj) handles 6 described hereinbefore. The haedles which have previously been dissociated from the settiuej-up members, are then seoaralcly restored to zero position which may be readily accomplished in any suitable manner. The slight modifications o be readily understood from olhm'ihg example. The setting" in hie, 9 carries loosely supported handle b'amtached-to a toothed dish which meshes z pinion (1 fixedly mounted on a restorg', which is well known. as regards in ehai iii-e iunctioii 'l' l-.a:lt Q equipped with a screw threaded e by which revolving siait caused to move longitudinally. hereby, radially disposed pins of the shaft f1 axially irojectihg iihs of the pin- 10119 0 and thus compel the latter to participate in the revolution of the shaft q 10). The revolving movement of the shaft i'oay be transmitted to the latter irom the "roam actuating member of the machine by means of toothed sector r (Fig. 11) mounted. so on the shaft f as engage, during the last part of the movement oi the main actuatiiu': member, a pinion a axedly mounted on the shalt g. time of the two parts, a or 7, must given. a suilcicnt Width to allow of 'a longitudiml displacemei of the shaft 9 Without thereby disengagm j the pinion a from the gear Wheel 9'. 7

Other possible modifications Within the scope of my invention will readily occur to those skilled in the ar 1 to which my invention appertains.
